GAS-LIQUID SEPARATOR OF COMPRESSION REFRIGERATING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a gas-liquid separator of a compression refrigerating machine, having high gas-liquid separation performance and enabling a space necessary for gas liquid separation to be greatly reduced.SOLUTION: The gas-liquid separator of a compression refrigerating machine, comprises: a container into which gas-liquid mixed fluid including refrigerant vapor, refrigerant liquid and/or oil inflows; a baffle which is disposed within the container and against which the gas-liquid mixed fluid inflowing in the container collides, so that liquid in the gas-liquid mixed fluid is primarily separated; an axial flow cyclone 22 which is disposed within the container and applies swirl flow to the primarily separated gas-liquid mixed fluid, so the liquid in the gas-liquid mixed fluid is secondarily separated; an upper channel FPextending toward an axial flow cyclone inlet opening part 22a constituted by the periphery of a casing 23 of the axial flow cyclone 22 and the inner surface of the container of a gas-liquid separator 20; and a lower channel FPconstituted by the inner surface of the casing 23 and the outer wall surface of a vapor outflow cylinder 24 for separating gas-liquid by the swirl flow of the axial flow cyclone 22. The gas-liquid mixed fluid passes through the upper channel FPand the lower channel FP, whereby gas and liquid are separated from each other.SELECTED DRAWING: Figure 3
